See here for the Colorado rules for its Charitable Contribution Subtraction. A taxpayer who both makes qualifying charitable contributions and claims the standard deduction on their federal income tax return for the same tax year can claim a Colorado charitable contribution subtraction for a portion of their contributions.
In general, the charitable contribution subtraction is calculated by subtracting $500 from the total amount of qualifying contributions made by the taxpayer during the tax year. For example, if a taxpayer who is eligible to take the charitable contribution subtraction made several qualifying contributions totaling $1,200 during the tax year, the taxpayer could claim a charitable contribution subtraction of $700. However, there are a variety of other federal rules that may affect the calculation of the subtraction.
The amount you saw on the Federal screen in Step by Step mode may not be the qualified amount. Since you are using a Desktop version of TurboTax, you can switch to Forms mode to view all of the Federal and State forms to determine how the amounts were calculated. Click on the Forms icon in the upper right area of your screen to switch to Forms mode.
